Dusshera, a prominent Hindu festival, fell on the 22nd of October this year (yesterday). On asking their Iphones about the festival, several users discovered that Siri got the name right, but the greeting wrong: the virtual assistant wished its owners 'Eid Mubarak' (not that big a deal when you actually consider how many festivals India actually celebrates, and how easy it can be for a human, let alone a virtual assistant to mess up).
